We have the era’s and they have stylistic themes and what have you, but even within those we have say the Saward era and the Cartmel era, or Douglas Adams… it’s nowhere near similar, partially because of the way the modern show sets up its arcs. Saward is the only one who really comes close to forcing Who into *his* shape, and writing (or ghostwriting…) a few of the stories. 
As to RTD and other writers, well, it’s all there in what you’re saying. Not only is he in overall control but also wrote half of the stories, and had a strong influence on at least one of the others. And Lucky Day must have been a bit of a shopping list story too, let’s be honest.
It’s also rather telling that Inua Ellams wrote a better Omega story than RTD, whilst still lifting from his own pre-existing work.
I wouldn’t necessarily describe recent Who as full auteur mode, but it’s increasingly obvious that no one was saying ‘how about not doing that?’ and a push to put it fully into auteur storytelling would be a catastrophic mistake.
